Description

  The present invention relates to a stop control technique for stopping the rotation of a reel provided in a slot machine.

  Conventionally, for example, three left, middle and right reels with a plurality of symbols are displayed. When the start switch is operated, all three reels start to rotate and the main lottery to determine the winning combination When one of the left, middle and right stop switches is operated, the reel corresponding to that stop switch is controlled to stop based on the lottery result. There is known a slot machine configured to determine that a winning is achieved when it is aligned on a predetermined active line and to give a predetermined profit to a player (see, for example, Patent Document 1). The slot machine described in Patent Document 1 is provided with a stop table that stores stop data that represents two states of stop and non-stop, ie, stop or not stop, and each reel at the time of operation of the stop switch. When the stop data corresponding to the frame number corresponding to each symbol is not stopped, the reel is advanced to the frame number to be stopped and stopped. A plurality of stop tables are provided, and are selectively used by sub-lottery using random numbers.

  However, in the slot machine described in Patent Document 1, a stop table that is alternatively selected from a plurality of stop tables by sub-lottery is used, that is, there is a stochastic element in the selection of the stop table. Despite operating the stop switch at an appropriate timing, depending on the result of the sub lottery, the reel is not stopped at the position corresponding to the result of the main lottery for determining the winning combination, which is inconvenient for the player. Inviting a natural situation. In particular, it is very unnatural for a player who is excellent in the skill of observing the symbols on the rotating reel and trying to operate the stop switch. This also applies to a slot machine that uses a program instead of the stop table to perform reel stop control.

  Recently, as shown in FIG. 16, for example, a game different from the game corresponding to the winning, such as a high probability replay or a lost game, is stochastic even though the big bonus is won in the main lottery. The reel stop control is performed so that the game corresponding to the winning in the main lottery is performed after the number of games or fixed games selected at the end of the period is over and the number of games or fixed games selected stochastically ends. There are slot machines with the ability to do. However, such a function has a problem as a function that harms the fairness of the game.

At this time, in the display frame 11, when the number of medals for the bet is one, three predetermined horizontal lines and three for a predetermined symbol, two predetermined diagonal lines are added, for a total of five. When the player stops in line with one of the active lines, a win is awarded, and a predetermined number of medals are paid out to the player by the hopper unit 43, or a predetermined profit such as replay is given to the player. Instead of paying out medals, credit medals may be stored inside.

  Random lottery results for determining the winning combination include a specific introduction game win (Big Bonus (BB) win), a specific game win (Regular Bonus (RB) Win), a small role win, and a replay win ( Replay win) and lost. In addition, the prize includes a specific introduction game prize (BB prize) related to the transition to the specific introduction game (BB game), a specific game prize (RB prize) related to the transition to the specific game (RB game), and a predetermined number of games. Small prize winning related to the payout of the medal and replay winning related to the execution of replay (Replay).

  The RB game refers to a game having a higher probability of winning than a normal game by allowing a specific winning game (JAC game) to be performed a plurality of times, and the BB game refers to a game having a higher probability of introducing an RB game. . When three predetermined symbols (for example, “7” or “Cross” in FIG. 6) are arranged on the active line, a BB win is awarded, and when there is a payout, medals are paid out, and from the normal game to the BB game. Migrate to Further, when three predetermined symbols (for example, “BAR” in FIG. 6) are arranged on the active line, an RB win is awarded, and when there is a payout, medals are paid out and the game shifts from the normal game to the RB game. Also, three predetermined symbols (for example, “Watermelon” and “Bell” in FIG. 6) are aligned on the active line, or a single winning symbol (for example, “Cherry” in FIG. 6) on the left reel 13L and the middle / right When one of the symbols on the reels 13M and 13R stops on the active line, each of the small roles is won and a predetermined number of medals are paid out. Further, for example, in FIG. 6, when three “Replays” are arranged on the active line, a Replay win is made, and the game can be played again under the same conditions as the previous game without inserting a new medal.

  If the result of the random lottery is BB winning, the reels 13L, 13M, and 13R are controlled to stop based on the BB winning. However, if no BB winning is awarded at this time, the BB winning is determined based on the BB winning. It will be carried over until it is allocated. The same applies to RB winning. The states where the BB winning or the RB winning is carried over are referred to as “per BB internal” and “per RB internal”, respectively. On the other hand, the small role winning is not carried over to the next game unless the result of the random number lottery is a small role winning in the game where the small role winning is not allocated. The same applies to Replay winning.

  The lottery means 110 performs random lottery for determining a winning combination, and includes a random number generation means 111, a random number extraction means 112, a lottery table 113, and a lottery determination means 114 as shown in FIG. The random number generator 111 generates a random number for lottery within a predetermined range (for example, 0 to 16383 in decimal number). The random number generation means 111 can be constituted by, for example, an oscillation circuit and a counter circuit that counts clock signals generated by the oscillation circuit (so-called hard random number). The random number generating means 111 can be constituted by means for generating random numbers by the average sampling method, or means for generating random numbers by adding prime numbers, for example. These means can be configured, for example, by causing the main CPU 61 to execute a predetermined program (so-called soft random number). Further, both hard random numbers and soft random numbers may be provided, and random numbers may be generated in a software manner based on the results. The random number extraction unit 112 extracts a random number generated by the random number generation unit 111, and extracts the random number generated by the random number generation unit 111 under a predetermined condition (for example, operation of the start switch 19 in this embodiment). Since the random number generation unit 111 is configured by a counter circuit or the like, the numerical value generated by the random number generation unit 111 is not strictly a random number. However, since the timing at which the start switch 19 is operated is considered to be random, the numerical value extracted by the random number extraction means 112 can be substantially handled as a random number.

  The lottery table 113 is a table in which whether or not a lot of random numbers in the entire range generated by the random number generator 111 is won is determined in a predetermined ratio. This lottery table 113 indicates whether the random number generator 111 generates all ranges of random numbers for BB winning, RB winning, small role winning, Replay winning, or lost. , Determined in advance at a predetermined rate. The lottery determination unit 114 compares the random number extracted by the random number extraction unit 112 with the lottery table 113 and determines the random number lottery result. The lottery determination unit 114 compares the random number extracted by the random number extraction unit 112 with the lottery table 113, and determines whether the result of the random lottery is BB win, RB win, small role win, Replay win, Judge whether it is lost.

  Based on the detection signals of the left / middle / right position sensors 55L, 55M, 55R and the number of pulses supplied to each stepping motor that drives the left / middle / right rotating reels 13L, 13M, 13R, -The rotation positions of the middle / right rotation reels 13L, 13M, and 13R are detected. That is, the detection means 120 detects the frame number corresponding to the symbol positioned in the middle stage of the display frame 11 when the left / middle / right rotation reels 13L, 13M, and 13R are rotating and when the rotation is stopped.

  The stop control means 125 performs stop control of the reels 13L, 13M, and 13R using the stop table 130 based on the random number lottery result of the lottery means 110. This stop table 130 is for determining the stop position of the symbol, and is the rotational position of the reels 13L, 13M, 13R when the stop switches 21L, 21M, 21R are operated (in this embodiment, the middle stage of the display frame 11). The number of sliding frames of the reels 13L, 13M, and 13R is determined in advance corresponding to the symbol (frame number corresponding to the symbol located at), and provided with stop tables 131, 132, and 133 for the left, middle, and right reels. . The reel stop control in this embodiment will be described in detail later.

  The winning determination unit 140 determines a winning when a predetermined symbol stops at a predetermined position. Specifically, the winning determination unit 140 determines a BB winning when three “7” or “cross” are aligned on the active line, and determines an RB winning when three “BAR” are aligned on the effective line. . Also, the winning determination means 140 determines that each of the “watermelon” or “bell” is aligned on the active line or the “cherry” of the left reel 13L is stopped on the effective line, respectively, to receive the small role winning. Further, the winning determination means 140 determines that the Replay winning is achieved when three “Replay” s are arranged on the active line. The payout control means 150 controls the hopper unit 43 to pay out the number of medals according to the winning mode when winning. Further, the payout control means 150 may increase the credit medals by the payout number instead of controlling the hopper unit 43.

  Next, reel stop control will be described in detail. Here, a case will be described in which the result of random number lottery in the lottery means 110 is “Bell” small winning combination, and the stop switches are operated in the order of the left / middle / right stop switches 21L, 21M, and 21R. FIG. 7 is a diagram for explaining reel stop control using a stop table, and FIG. 8 is a diagram for explaining stop tables 131, 132, 133 for left, middle, and right reels.

  As shown in FIG. 7A, when the left stop switch 21L is first operated during the rotation of the left / middle / right reels 13L, 13M, and 13R that has started rotating by the operation of the start switch 19, the left reel 13L stop control is performed. Here, since the result of the random number lottery performed by the lottery means 110 performed at the time of operating the start switch 19 is “Bell”, the left reel stop table 131 corresponding to the winning combination “Bell”, that is, , The left reel stop table 131 is set so as to draw “bell” into the active line.

  For example, assume that the rotation position of the left reel 13L when the left stop switch 21L is operated is in a state as shown in FIG. At this time, as shown in FIG. 7C, when the “bell” is stopped at the upper stage of the display frame 11, the frame is advanced by 3 frames. As shown in FIG. When stopped, the frame is advanced by 4 frames. When the “bell” is stopped at the lower stage of the display frame 11 as shown in FIG.

  The stop table 130 is provided corresponding to each result of random number lottery. That is, it is provided corresponding to each of BB winning, RB winning, each small role winning, Replay winning, and lose. For example, only one stop table 131 for the left reel shown in FIG. 8 is provided corresponding to the case where the left stop switch 21L is first operated in the small role winning of “Bell”. Then, the stop control means 125 first selects the stop table 130 corresponding to the random number lottery result. Next, when the stop switches 21L, 21M, and 21R are operated, the frame numbers corresponding to the symbols of the reels 13L, 13M, and 13R located in the middle stage of the display frame 11 are detected by the detecting means 120, and the slips associated with the frame numbers are detected. The number of frames is extracted from the selected stop table 130. Here, if the number of sliding frames is “0”, the rotation of the reels 13L, 13M, 13R is immediately stopped. That is, when the number of sliding frames is “0”, the symbols displayed in the upper part of the display frame 11 when the stop switches 21L, 21M, and 21R are operated are stopped and displayed in the upper part of the display frame 11 as they are. . When the number of sliding frames is “1”, the reels 13L, 13M, and 13R are rotated and stopped by one frame. That is, when the number of sliding symbols is “1”, the symbols displayed on the upper stage of the display frame 11 when the stop switches 21L, 21M, and 21R are operated are 1 in the rotation direction of the reels 13L, 13M, and 13R. The frames are shifted and stopped and displayed in the middle of the display frame 11.

  Therefore, in FIG. 8, when the symbol of each frame number is positioned in the middle stage of the display frame 11 when the left stop switch 21L is operated, the number of sliding frames on the left reel stop table 131 is advanced, so that the left reel 13L is stopped. The position, that is, the frame number of the symbol positioned in the middle of the display frame 11 when the left reel 13L is stopped is the frame number shown in the “stop position” column of “left reel” in FIG. For example, when the symbol of frame number “0” is positioned in the middle stage of the display frame 11 when the left stop switch 21L is operated, the number of sliding frames advances by “3”. The frame number of the symbol to be played is “18”.

  As a result, the frequency at which the symbol of each frame number stops in the middle of the display frame 11 is the number of times shown in the “stop frequency” column of “left reel” in FIG. For example, the frequency at which the symbol with frame number “0” stops in the middle of the display frame 11 is “0” times, and the frequency at which the symbol with frame number “2” stops in the middle of the display frame 11 is “2” times. . In FIG. 8, the fact that the symbol of frame number “2” stops at the middle stage of display frame 11 means that the “bell” of frame number “3” stops at the lower stage of display frame 11. Therefore, in the left reel stop table 131 of FIG. 8, the frequency at which the “bell” of the frame number “3” stops at the upper, middle, and lower stages of the display frame 11 is two times, two times, and twice, respectively. It can be seen that the frequencies at which the “bells” of the numbers “8”, “13”, and “19” stop at the upper, middle, and lower stages of the display frame 11 are twice, once, and twice, respectively. That is, in the left reel stop table 131 in FIG. 8, the “bell” always stops at any one of the upper, middle, and lower stages of the display frame 11.

  Similarly, when the symbol of each frame number is located in the middle stage of the display frame 11 when the middle stop switch 21M is operated, the number of sliding frames on the middle reel stop table 132 is advanced, so the stop position of the middle reel 13M, That is, the frame number of the symbol positioned in the middle stage of the display frame 11 when the middle reel 13M is stopped is the frame number shown in the “stop position” column of “middle reel” in FIG. For example, when the symbol of frame number “0” is positioned in the middle stage of the display frame 11 when the middle stop switch 21M is operated, the number of sliding frames advances by “2”, so that it is positioned in the middle stage of the display frame 11 when the middle reel 13M is stopped. The frame number of the symbol to be played is “19”.

  As a result, the frequency at which the symbol of each frame number stops at the middle stage of the display frame 11 is the number of times shown in the “stop frequency” column of “middle reel” in FIG. For example, the frequency at which the symbol with frame number “0” stops in the middle of the display frame 11 is “0” times, and the frequency at which the symbol with frame number “2” stops in the middle of the display frame 11 is “2” times. . In the “middle reel” of FIG. 8, the symbol of the frame number “2” stops at the middle stage of the display frame 11. This means that the “bell” of the frame number “1” is at the upper stage of the display frame 11 and This means that “3” “bell” stops at the lower part of the display frame 11. Therefore, in the middle reel stop table 132 in FIG. 8, the frequency at which the “bells” of the frame numbers “1”, “13”, and “18” stop at the upper and middle stages of the display frame 11 is twice. The frequency at which the “bell” of the frame number “8” stops at the upper and middle stages of the display frame 11 is 3 times and 3 times, respectively, and the “bell” of the frame number “3” is displayed on the display frame 11. It can be seen that the frequency of stopping at the upper, middle and lower stages is once, twice and twice, respectively. When the “bell” of the frame number “3” stops at the lower stage of the display frame 11, the “bell” of the frame number “1” stops at the upper stage of the display frame 11. That is, in the middle reel stop table 132 shown in FIG. 8, the “bell” always stops at either the upper or middle stage of the display frame 11.

  Similarly, when the symbol of each frame number is positioned in the middle of the display frame 11 when the right stop switch 21R is operated, the number of sliding frames on the right reel stop table 133 is advanced, so the stop position of the right reel 13R, That is, the frame number of the symbol positioned in the middle stage of the display frame 11 when the right reel 13R is stopped is the frame number shown in the “stop position” column of “right reel” in FIG. For example, when the symbol of frame number “0” is positioned in the middle stage of the display frame 11 when the right stop switch 21R is operated, the number of sliding frames is “0”, so that the middle frame of the display frame 11 is stopped when the right reel 13R is stopped. The frame number of the located symbol is “0”.

  As a result, the frequency at which the symbol of each frame number stops in the middle of the display frame 11 is the number of times shown in the “stop frequency” column of “right reel” in FIG. For example, the frequency at which the symbol with frame number “0” stops in the middle of the display frame 11 is “5” times, and the frequency at which the symbol with frame number “2” stops in the middle of the display frame 11 is “0” times. . In the “right reel” of FIG. 8, the symbol with frame number “0” stops at the middle stage of the display frame 11 means that the “bell” with frame number “1” stops at the lower stage of the display frame 11. means. Therefore, in the right reel stop table 133 in FIG. 8, the frequency at which the “bell” of the frame numbers “1”, “6”, and “14” stops at the lower part of the display frame 11 is 5 times. It can be seen that the frequency at which the “bells” of the numbers “11” and “19” stop at the lower part of the display frame 11 is three. That is, in the right reel stop table 133 shown in FIG. 8, the “bell” always stops at the lower stage of the display frame 11.

  FIG. 9 is a flowchart of a reel stop control procedure, and FIG. 10 is a diagram for explaining a procedure for aligning “bells” on an effective line according to the procedure of FIG. FIG. 9 illustrates a case where the result of the random number lottery in the lottery means 110 is “Bell”, where the stop switch is operated in the order of the left / middle / right stop switches 21L, 21M, and 21R. -The case where the right stop switches 21M and 21R are operated first is omitted.

  In FIG. 9, when the left stop switch 21L is first operated during rotation of the left / middle / right reels 13L, 13M, 13R (# 10), the rotation position of the left reel 13L at the time of the operation is shown in FIG. The stop position of the left reel 13L is determined using the number of sliding frames on the left reel stop table 131 shown (# 11), and the stop position of the “bell” is determined (# 12). Here, as described with reference to FIG. 8, the “bell” stops at any one of the upper, middle, and lower stages of the display frame 11, and as shown in FIG.・ It is divided into the following three cases.

  When the stop position of “bell” is the upper stage, the upper / middle table set so that “bell” stops at either the upper stage or the middle stage is selected as the middle reel stop table 132 (# 13). . The middle reel stop table 132 shown in FIG. 8 is an example of the “upper / middle table”. Then, when the middle stop switch 21M is operated (# 14), the middle reel using the rotational position of the middle reel 13M at the time of the operation and the number of sliding frames of the upper / middle table selected in step # 13. The stop position of 13M is determined (# 15), and the stop position of the “bell” is determined (# 16). Here, as described in FIG. 8, “bell” stops at either the upper or middle stage of the display frame 11, and as shown in FIG. 10B, the stop position of “bell” is 2 in the upper or middle stage. Divided into two cases.

  When the stop position of “bell” is the upper stage, the upper table set so that “bell” stops at the upper stage is selected as the right reel stop table 133 (# 17), If the stop position is in the middle position, the lower table set so that the “bell” stops in the lower position is selected (# 18). The right reel stop table 133 shown in FIG. 8 is an example of the “lower table”. When the right stop switch 21R is operated (# 19), the rotational position of the right reel 13R at the time of the operation and the sliding table of the upper table selected in step # 17 or the lower table selected in step # 18. The stop position of the right reel 13R is determined using the number (# 20). When the upper table is selected in step # 17, “bells” are aligned on the upper effective line as shown in FIG. 10C, and when the lower table is selected in step # 18, As shown in FIG. 10 (D), the “bells” are aligned on the effective line diagonally downward.

  On the other hand, when the stop position of “bell” is in the middle in step # 12, a middle table set so that “bell” stops in the middle is selected as the middle reel stop table 132 (# 21). ). Then, when the middle stop switch 21M is operated (# 22), the rotation position of the middle reel 13M at the time of the operation and the number of sliding pieces of the middle table selected at step # 21 are used. A stop position is determined (# 23). Here, as shown in FIG. 10E, the “bell” stops at the middle stage. Next, as the right reel stop table 133, a middle table set so that the “bell” stops at the middle stage is selected (# 24). Then, when the right stop switch 21R is operated (# 25), the rotation position of the right reel 13R at the time of the operation and the number of sliding pieces of the middle table selected in step # 24 are used. A stop position is determined (# 26). Then, as shown in FIG. 10F, the “bells” are aligned on the middle effective line.

  In step # 12, when the stop position of “bell” is in the lower stage, the middle / lower table set so that “bell” stops in the middle or lower stage is selected as the middle reel stop table 132. (# 27). When the middle stop switch 21M is operated (# 28), the middle reel using the rotational position of the middle reel 13M at the time of operation and the number of sliding frames of the middle and lower tables selected in step # 27. The stop position of 13M is determined (# 29), and the stop position of the “bell” is determined (# 30). Here, as shown in FIG. 10G, the stop position of the “bell” is divided into two cases of the middle stage and the lower stage.

  When the stop position of “bell” is in the middle, the upper table set so that “bell” stops at the upper stage is selected as the right reel stop table 133 (# 31), When the stop position is in the lower stage, the lower table set so that the “bell” stops in the lower stage is selected (# 32). When the right stop switch 21R is operated (# 33), the rotational position of the right reel 13R at the time of the operation and the sliding table of the upper table selected in step # 31 or the lower table selected in step # 32 are displayed. The stop position of the right reel 13R is determined using the number (# 34). When the upper table is selected at step # 31, "bells" are aligned on the diagonally upward active line as shown in FIG. 10H, and the lower table is selected at step # 32. As shown in FIG. 10I, “bells” are aligned on the lower effective line.

  Thus, in this embodiment, when the result of the random number lottery in the lottery means 110 is the small role winning of “Bell” and the left stop switch 21L is operated first, the left reel stop table 131 is “ There is provided only one stop table in which the “bell” is set to stop at the upper, middle and lower stages of the display frame 11. Therefore, the stop position of the left reel 13L is uniquely determined from the rotational position of the left reel 13L when the left stop switch 21L is operated and the number of sliding frames of the left reel stop table 131.

  Further, when the middle stop switch 21M is operated second after the left stop switch 21L, the middle reel stop table 132 is set so that “bell” stops at the upper and middle stages of the display frame 11. Upper / middle table, middle table set to stop “Bell” in the middle of display frame 11, and lower / middle table set to stop “Bell” in the middle / lower of display frame 11 The three stop tables are provided. Then, the stop table to be used is determined based on the stop position of the left reel 13L. Therefore, the stop position of the middle reel 13M is unambiguous from the stop position of the left reel 13L, the rotation position of the middle reel 13M when the middle stop switch 21M is operated, and the number of sliding frames of the middle reel stop table 132 used. It is decided.

  Further, when the right stop switch 21R is operated third, the right reel stop table 133 includes an upper table set so that “bell” stops at the upper stage of the display frame 11, and “bell”. Is provided with three stop tables: a middle table set to stop at the middle of the display frame 11 and a lower table set to stop “Bell” at the bottom of the display frame 11. Then, a stop table to be used is determined based on the stop position of the left reel 13L and the stop position of the middle reel 13M. Therefore, from the stop position of the left reel 13L, the stop position of the middle reel 13M, the rotation position of the right reel 13R when the right stop switch 21R is operated, and the number of sliding pieces of the stop table 133 for the right reel to be used, The stop position of the reel 13R is uniquely determined.

  That is, in this embodiment, in the reel stop control by the stop control means 125 after the random number lottery for determining the winning combination by the lottery means 110 is performed, each reel when the stop switches 21L, 21M, and 21R are operated. There is no stochastic element in the relationship between the rotation positions of 13L, 13M, and 13R and the stop positions of the reels 13L, 13M, and 13R after the operation of the stop switches 21L, 21M, and 21R. For this reason, if the stop switch is operated at an appropriate timing, the reel can be surely stopped at the winning stop position when the result of the random number lottery is a win. Therefore, it is possible to prevent the occurrence of an unnatural situation as in the prior art, and to ensure the fairness of the game.

  In this embodiment, each function of the main control board 63 shown in the functional block diagram of FIG. 5 can be realized by the main CPU 61 executing a slot machine program stored in the ROM 67. That is, in this embodiment, the main CPU 61 corresponds to a computer, and the ROM 67 corresponds to a computer-readable recording medium on which a slot machine program is recorded. In this case, in the above-described embodiment, the ROM 67 is configured by a memory mounted on the main control board 63. However, the present invention is not limited to this, and a DVD-ROM, a CD-ROM, an MO, a removable hard disk, a flash memory, and a ferroelectric substance are used. You may comprise with a recording medium which can be attached or detached to the slot machine 1, such as a memory.

  The present invention is not limited to the above embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the main control board 63 and the sub control board 73 are provided with separate control boards, each including a CPU and a memory. However, the present invention is not limited to this, and a single control board is provided. You may comprise with one CPU and one memory. In the above embodiment, the slot machine has three reels, but the present invention is not limited to this, and a slot machine having four or more reels may be used. In the above embodiment, the number of effective lines is 5. However, the present invention is not limited to this.

  For example, in the above-described embodiment, the reel stop tables 131, 132, and 133 when operated in the order of the left / middle / right stop switches 21L, 21M, and 21R are described, but the present invention is not limited thereto. For example, the reel stop tables 131, 132, 133 may be set for each operation order of the stop switches 21L, 21M, 21R. That is, for example, when the “Bell” small role winning is operated in the order of the middle / left / right stop switches 21M, 21L, 21R, only one middle reel stop table 132 is provided, and the middle stop switch 21M The stop position of the middle reel 13M is determined from the rotational position of the middle reel 13M during the operation and the number of sliding frames of the one middle reel stop table 132. Next, the left reel stop table 131 to be used is determined from the stop position of the middle reel 13M, the rotational position of the left reel 13L when the left stop switch 21L is operated, and the determined number of sliding symbols of the left reel stop table 131. And the stop position of the left reel 13L is determined. Next, the right reel stop table 133 to be used is determined from the stop position of the middle reel 13M and the stop position of the left reel 13L, and the rotation position of the right reel 13R when the right stop switch 21R is operated and the determined right reel. The stop position of the right reel 13R is determined from the number of sliding frames on the stop table 133 for use. Also in this form, the same effect as the above embodiment can be obtained.

  In the above embodiment, the reel stop control by the stop control unit 125 after the random number lottery for determining the winning combination by the lottery unit 110 is performed regardless of the random number lottery result of the lottery unit 110 (that is, the random number lottery). (Even if the result of the lottery is lost), the rotation positions of the reels 13L, 13M, and 13R when the stop switches 21L, 21M, and 21R are operated, and the reels after the operation of the stop switches 21L, 21M, and 21R There is no stochastic element in the relationship with the stop positions of 13L, 13M, and 13R, but instead, there is no stochastic element in the above relationship except when the result of random lottery by the lottery means 110 is lost. It may be. Even in this form, if the stop switch is operated at an appropriate timing, the reel can be surely stopped at the stop position where the winning is achieved when the result of the random number lottery is a win. Therefore, it is possible to prevent the occurrence of an unnatural situation as in the prior art, and to ensure the fairness of the game. If the result of the random number lottery is lost, no profit (for example, medal payout) is originally given to the player. Therefore, if the random number lottery result of the lottery means 110 is lost, each stop switch 21L, There is a stochastic factor in the relationship between the rotational position of each reel 13L, 13M, 13R during operation of 21M, 21R and the stop position of each reel 13L, 13M, 13R after operation of each stop switch 21L, 21M, 21R Even so, there is no problem in ensuring the fairness of the game.

  Further, the reel stop control by the stop control means 125 and the left / middle / right reel stop tables 131, 132, 133 are not limited to the above embodiment. FIG. 11 is a diagram illustrating an example of another left / middle / right reel stop table 131, 132, 133. FIG. In the example of FIG. 11, as in the above embodiment, it is assumed that the left, middle, and right stop switches 21L, 21M, and 21R are operated in the order of the “Bell” small role winning.

  In the left reel stop table 131 of FIG. 11, the frequency at which the “bells” of the frame numbers “3”, “8”, “13”, and “19” stop at the middle stage of the display frame 11 is 5 times. It can be seen that the frequency at which the “bell” of the frame number “19” stops at the lower part of the display frame 11 is one time. That is, in the left reel stop table 131 of FIG. 11, the frequency at which “bell” stops at the middle stage of the display frame 11 is 20 out of 21 times, and “bell” is placed at the lower stage of the display frame 11 for the remaining one time. It comes to stop.

  Further, in the middle reel stop table 132 of FIG. 11, the frequency at which the “bell” of the frame number “1” stops at the middle stage of the display frame 11 is one time, and the frame numbers “3”, “8”, “13” "Bell" stops at the middle stage of the display frame 11, and the frequency at which the "bell" of the frame number "18" stops at the middle stage of the display frame 11 is four times. . That is, in the middle reel stop table 132 in FIG. 11, the “bell” always stops at the middle stage of the display frame 11.

  Further, in the right reel stop table 133 in FIG. 11, the frame numbers “1”, “6”, and “11” “bell” are stopped at the middle part of the display frame 11 every five times. It can be seen that the frequency at which the “bell” of “14” and “19” stops at the middle stage of the display frame 11 is three times. That is, in the right reel stop table 133 in FIG. 11, the “bell” always stops at the middle stage of the display frame 11.

  In the reel stop control by the stop control means 125 in this case, the stop position of the left reel 13L is uniquely determined by the rotation position of the left reel 13L when the left stop switch 21L is operated and the stop table 131 for the left reel. . The stop position of the intermediate reel 13M is uniquely determined by the rotation position of the intermediate reel 13M when the intermediate stop switch 21M is operated and the intermediate reel stop table 132. Further, the stop position of the right reel 13R is uniquely determined by the rotation position of the right reel 13R when the right stop switch 21R is operated and the stop table 133 for the right reel.

  Also in this modified form, in the reel stop control by the stop control means 125 after the random number lottery for determining the winning combination by the lottery means 110 is performed, the reels 13L, 13L, 21R, 21R, 21R when the stop switches 21L, 21M, 21R are operated. There is no stochastic element in the relationship between the rotational position of 13M, 13R and the stop position of each reel 13L, 13M, 13R after operation of each stop switch 21L, 21M, 21R. For this reason, if the stop switch is operated at an appropriate timing, the reel can be surely stopped at the stop position where the winning is achieved when the result of the random lottery is the winning combination. Therefore, similarly to the above embodiment, it is possible to prevent the occurrence of an unnatural situation as in the prior art, and to ensure the fairness of the game.

  In the above embodiment, a case where only one stop table (the left reel stop table 131 in the above embodiment) corresponding to the first operated stop switch (the left stop switch 21L in the above embodiment) is provided will be described. However, the present invention is not limited to this, and a plurality of stop tables corresponding to the stop switch operated first may be provided, and the stop tables to be used may be determined in a predetermined order. FIG. 12 is a diagram illustrating another example of determining the left reel stop table 131 used when the left stop switch 21L is first operated.

  As described in the above embodiment, when the result of random number lottery in the lottery means 110 is BB winning, the reels 13L, 13M, 13R are controlled to stop based on the BB winning. At this time, a BB winning is assigned. Otherwise, this BB winning will be carried over until a BB prize is awarded. The same applies to RB winning. Therefore, in this modification, a plurality of (for example, three in this modification) left reel stop tables 131 are provided in advance, and when the BB winning is carried over, the stop tables to be used in a predetermined order are determined. Like to do.

  That is, in FIG. 12, as the left reel stop table 131, “7” is set to stop at the upper stage of the display frame 11, and “7” is stopped at the middle stage of the display frame 11. A stop table B that is set and a stop table C that is set so that “7” stops at the lower stage of the display frame 11 are provided. When the result of the random number lottery performed in the lottery means 110 when the start switch 19 is operated is BB winning, and the left stop switch 21L is operated first, the stop control means 125 first stops the left reel. The stop table A is used as the table 131. At this time, for example, if the player's operation is not successful and “777” is not aligned on the active line and the BB winning is not awarded, the BB winning is carried over. When the left stop switch 21L is first operated in the next game, the stop control means 125 uses the stop table B as the left reel stop table 131. Further, at this time, if “777” is not aligned on the active line and the BB winning is not made, the BB winning is carried over again, and when the left stop switch 21L is operated for the first time in the next game, The stop control means 125 uses the stop table C as the left reel stop table 131. If the BB winning is not awarded at this time, the BB winning is carried over again, and when the left stop switch 21L is operated for the first time in the next game, the stop control means 125 stops the stop for the left reel. The stop table A is used as the table 131.

  Here, the stop table (for example, the middle reel stop table 132) corresponding to the second operated stop switch (for example, the middle stop switch 21M) is a plurality of stop tables (as the left reel stop table 131). In FIG. 12, a stop table corresponding to the stop table (for example, stop table A) provided corresponding to each of the stop tables A, B, and C) and used as the left reel stop table 131 is used. The stop table (for example, the right reel stop table 133) corresponding to the third operated stop switch (for example, the right stop switch 21R) is the combination of the stop tables used for the first and second (for example, the left and middle). Each combination of the stop tables 131 and 132 for reels) and the combination of the stop tables used first and second (for example, the stop tables used as the left and middle reel stop tables 131 and 132). The stop table corresponding to the combination) is used.

  Thus, in this modified embodiment, the stop control means 125 stores the stop table used as the left reel stop table 131 in, for example, the RAM 65, and in the state where the BB winning is carried over, the left reel stop table. The stop table used as 131 is switched to a stop table A, B, C, A,. Then, for example, when the carry-over of the BB winning is completed due to the BB winning being allocated, the stop control unit 125 resets the stop table stored in the RAM 65. That is, when the next new BB is won, the left reel stop table 131 is used again from the stop table A.

  According to this modification, in the reel stop control by the stop control means 125 after the random number lottery for determining the winning combination by the lottery means 110 is performed, each reel when the stop switches 21L, 21M, and 21R are operated. There is no stochastic element in the relationship between the rotation positions of 13L, 13M, and 13R and the stop positions of the reels 13L, 13M, and 13R after the operation of the stop switches 21L, 21M, and 21R. For this reason, the effect similar to the said embodiment can be acquired.

  Although FIG. 12 illustrates the case where the left stop switch 21L is operated first, the same stop control is performed also when the middle / right stop switches 21M and 21R are operated first, for example. That is, a plurality of stop tables are provided as the intermediate reel stop table 132, and when the intermediate stop switch 21M is operated first, the stop control means 125 uses the stop table used from the plurality of intermediate reel stop tables 132. What is necessary is just to determine in the order decided beforehand. Also, a plurality of stop tables are provided as the right reel stop table 133, and when the right stop switch 21R is operated first, the stop control means 125 uses the stop table used from the plurality of right reel stop tables 133. What is necessary is just to determine in the order decided beforehand. Then, as in FIG. 12, the second stop table may be determined based on the first used stop table, and the third stop table may be determined based on the first and second stop tables.

  In the description of FIG. 12, when the carry-over of the BB winning is completed, the stop control unit 125 resets the stop table stored in the RAM 65, and again as the left reel stop table 131 at the next new BB winning. However, it is not limited to this, and the stop table stored in the RAM 65 is not reset when the carry-over of the BB win is completed. For example, the carry-over of the previous BB win is completed at the next new BB win. If it is the stop table B at the time, it may be used in order from the next stop table C.

  Although FIG. 12 illustrates the case where the BB winning is carried over, the present invention is not limited to this. For example, the same stop control may be performed when the RB winning is carried over. Further, the present invention is not limited to the case of carrying over BB winning or RB winning, and may be applied to small winning combination. FIG. 13 illustrates an example of determining the left reel stop table 131 used when the left stop switch 21L is operated for the first time when this modified form is applied to the small role winning (“Bell” winning in FIG. 13). It is a figure to do.

  In FIG. 13, as the stop table 131 for the left reel, a stop table D in which “bell” is set to stop in the middle stage of the display frame 11, and “bell” is set to stop in the lower stage of the display frame 11. The stop table E and the stop table F set so that the “bell” stops at the upper stage of the display frame 11 are provided. Then, when the result of random lottery performed in the lottery means 110 when the start switch 19 is operated is a bell win, the “bell win count” stored in the RAM 65 is incremented. When the left stop switch 21L is operated for the first time, the stop control means 125 extracts the “bell winning number” stored in the RAM 65, for example, based on the remainder obtained by dividing the “bell winning number” by 3. Determine the stop table to be used. In other words, the stop control means 125 uses the stop table D as the left reel stop table 131 when the remainder of dividing the “bell winning number” by 3 is “1”, and the left reel stop table when the remainder is “2”. The stop table E is used as 131, and the stop table F is used as the left reel stop table 131 when the remainder is "0".

  Then, as in the case of FIG. 12, the stop table corresponding to the second operated stop switch is determined corresponding to the first used stop table and corresponds to the third operated stop switch. The stop table to be used may be determined corresponding to the stop table used first or second. Note that FIG. 13 illustrates the case where the left stop switch 21L is operated first, but similarly to the case of FIG. 12, for example, the same applies when the middle / right stop switches 21M and 21R are first operated. It is possible to perform stop control. In the form of FIG. 13 as well, in the reel stop control by the stop control means 125 after the random number lottery for determining the winning combination by the lottery means 110 is performed as in the form of FIG. , 21R has no stochastic element in the relationship between the rotation position of each reel 13L, 13M, 13R and the stop position of each reel 13L, 13M, 13R after operation of each stop switch 21L, 21M, 21R. For this reason, the effect similar to the said embodiment can be acquired.

  As described above, in the present invention, as shown in the schematic diagram of FIG. 14, after the random number lottery is performed by operating the start switch 19, only one is provided when the left stop switch 21L is operated. Since the reel stop control is performed using the left reel stop table 131, the rotation position of the left reel 13L when the left stop switch 21L is operated and the stop position of the left reel 13L after the operation of the left stop switch 21L are determined. There is no stochastic element in the relationship. On the other hand, in the schematic diagram of FIG. 15 showing the comparative example, when the left stop switch is operated after the random number lottery is performed by the operation of the start switch, for example, the three left reel stop tables are provided. For example, the reel stop control is performed using a stop table selected with a probability of 1/3 from the above, so that the rotation position of the left reel when the left stop switch is operated and the left reel after the left stop switch is operated There is a stochastic element in the relationship with the stop position. For this reason, in the example of FIG. 15, an unnatural situation may occur as in the past, or the fairness of the game may be harmed.

  In addition, although the example which performs reel stop control using a stop table was demonstrated in the said embodiment and modification, this invention is not restricted to this, You may make it perform reel stop control by a program. Even in this case, it is possible to obtain the same effect as the above embodiment.
